An abrasive grinding machine (11) is disclosed which comprises workpiece conveying means (14) carried in a horizontal position by a frame (12) with a grinding head (15) disposed in overlying relation thereto. The conveying means (14) includes a flexible endless conveyor belt (22) the upper flight of which passes over a rigid planar backing surface. The grinding head (15) includes an abrasive belt (27) that moves in a direction opposite the conveyor belt (22). A back-up roller (31) is rotatably disposed in a recess (21) in the bed (13) in opposition to a drive roller (28) of the grinding head (15). The back-up roller (31) slightly elevates the conveyor belt (22) from the rigid support surface of the bed (13). The belt (22) is thus able to deflect and conform to a warped or twisted workpiece as it moves through the grinding area, resulting in uniform deslagging of each workpiece.
